Patent CA-2088389-C (CA)
Title: Noble metal on rare earth modified silica alumina as hydrocarbon conversion catalyst
Inventor: SOLED STUART L
IPC: C10G45/12
Filed: 1993-01-29
Granted: 2001-04-17
Abstract: Rare earth oxides, such as Nd2O3 disperse onto the surface of SiOg/A12O3 and act as weakly basic titrants. This lowers the acidity of SiO2/A12O3 to close to that of chlorided alumina, as shown by model compound reaction tests. This support also disperses a noble metal such as Pt much better than undoped SiO2/Al2O3 and similar to chlorided alumina. Platinum on the rare earth modified silica alumina can function as a hydrocarbon conversion catalyst in reactions where Pt/chlorided Al2O3 is used, such as in reforming, and isomerization, especially wax isomerization.

Patent CA-2095755-C (CA)
Inventor: BAUGHER MARK J
IPC: H04L12/433
Filed: 1993-05-07
Granted: 1999-01-26
Abstract: A  data  processing  system  for  regulating  access  to  a communication  network  is  disclosed  herein.   The  data processing  system  employs  a  component  that  can  be implemented in hardware logic or software.  The component regulates access to the priority queue or transmit channel that is attached to the shared medium local area network section.  All  access  to  the  priority  queue  or  transmit channel must pass through this component,  thus subjecting all communication transactions to rejection or tracking by the component. The component allocates a frame size based on the information to be transmitted and the priority to assure the transmission will be completed in line with the quality of service required.  The component monitors the rate and size of messages to assure that an application's actual throughput does not exceed its negotiated throughput.  The component, moreover, is capable of operating in correction mode  where  throughput  and  frame  size  violations  are prevented  and  reported.   Alternatively,   the  component operates in detection mode where violations are recorded and reported to an application.

Abstract: One of the internal key telephone sets coupled to a key telephone apparatus capable of automatic call distribution operates as a supervisor and other operate as agents.      Under the automatic call distribution, the statuses of the agents and their number are stored in a memory. The stored statuses of the agents are informed to the supervisor.      Each key telephone set has a display unit. When one of the key telephone sets operates as the supervisor, the informed statuses and their number are displayed on the display unit of the supervisor. With identification data of a specific agent, the status of the specific agent is displayed on the display unit of the supervisor. To operate one of the key telephone sets as the supervisor and other the agents, first, a password is entered from one of the key telephone sets. The input password is compared with a first reference password for the supervisor and with a second reference password for the agents. When the input password is equivalent to the first password, the telephone set is registered as the supervisor. On the other hand, when equivalent to the second password, the telephone set is registered as the agent.

Title: Automatic shutoff valve
Inventor: PHILLIPS PAUL E
IPC: F16K31/28
Filed: 1994-11-02
Granted: 1998-09-29
Abstract: A two-stage float actuated shut-off valve for use in underground fuel storage tanks utilizes a drop tube coaxially mounted within the storage tank fill pipe. Fuel flowing into the tank is passed through the drop tube which projects downwardly into the interior of the tank to a valve housing located at the lower end of the drop tube.  Floats slidably mounted in a recessed area in the housing outside of the drop tube within the tank independently operate pivoted valve doors to a closed position within the valve housing, a lower float closing one valve door to block a major portion of incoming fuel flow passage when the level of fuel in the storage tank reaches a predetermined first level and a second upper float causing the secondary valve door to overlap an aperture in the main valve door to almost completely close the flow of fuel to the tank.

Abstract: Devices are described for fitting into pressurised individually packaged beverages (typically canned beers, ales and stouts), by which gas at high pressure is stored within the package for jetting into the beverage as the package is opened to atmosphere. One embodiment comprises a length of tube (10) having a gas jetting orifice (14) which in use is submerged below the beverage in a pressurised can having a gaseous headspace, which can be used to charge the tube with gas during the passage of the filled can (16) along a conventional canning line, on which the can is inverted after filling which brings the orifice into the gaseous headspace. A men preferred design of device comprises a moulded plastics capsule (34; 50; 78) secured near the bottom of a can (20, 88) with an internal, preferably central, pipe (56; 62; 80) to provide a liquid seal to prevent loss of gas when the can is inverted from the uprigth position, and an airlock when the can is upright, to prevent beverage which has entered the capsule from leaving it when the can is opened to atmosphere.

Patent CA-2152702-C (CA)
Inventor: HILDEBRANDT GUSTAV
IPC: B29C41/28
Filed: 1995-06-27
Granted: 1999-10-26
Abstract: This invention concerns a sheet for producing plastic films with a tear-resistant layer and a plastic layer that is applied to the former and has a surface that faces away from the tear-resistant layer and is suitable for applying liquid or pasty plastics for the plastic film to be produced. The surface of the layer of plastic which is preferably a negative of a relief pattern consists of polypropylene. The sheet permits a high fidelity in reproduction of the relief pattern plus a long lifetime as well. The sheet may be relatively thin, so a great length can be wound up on a roll. Therefore, great lengths of a plastic film can be produced in one piece by casting or spreading liquid plastic on the sheet. Therefore, the conversion time required for the manufacturing installation is short, which has a positive effect on the price of the product.

Abstract: A retreat  restricting member  for  restricting the retreat of a pinion in an advanced state of the pinion on an output shaft and in a resulting meshed state of a pinion gear with a ring gear is engaged with a pair of pins rotatably, the pins being each attached to a thrust ring.   In a rotation restricting member for restricting the rotation of the pinion, upon meshing of the pinion gear with the ring gear, the front end of a rotation restricting bar is disengaged from a recess of a rotation restricting plate and falls to the rear end side of the thrust ring, thereby releasing the rotation-restricted state of the pinion.   Further,  engaging portions of the rotation restricting member come into engagement with engaging recesses of the retreat restricting member to hold the posture of the member, thereby inhibiting the retreat of the pinion.
